After almost a year of use, It’s time for a long term update for the One Up EDC Tool. After I got back from my trip to South America where I broke the mount for my hand pump that attached the pump to my bike, I started looking around for a new hand pump to attach to my bike. The pump itself was also starting to wear out, it being our only pump that Anthony and I took on our trip, it got used a lot to up the tire pressure before rides, fix flats, and even seat multiple tubeless tires.
I went to Obsession: Bikes, my local shop and they had some One Up pumps. After enjoying my EDC tool, I was interested to see if their hand pump would surprise me again with lots of features.
Generally, hand pumps are a last resort and most are built that way. Some only work long enough to fix a couple flat tires, then falling apart or not building enough pressure to fully inflate a tube. The One Up pump however, is not like other pumps.
The pump comes in two different sizes, 100cc and 70cc, cc being the volume of air per pump. They both have some nifty features that most other pumps do not. Both can hold the One Up EDC Tool, and the 100cc pump, which is longer, can hold the tool a CO2 screwed in the bottom, with the 70cc version only being able to hold the EDC tool, or a CO2 due to the shorter length. The pumps have a removable tip that will screw onto a CO2 cartridge to quickly fill up a tire/tube. Both are able to be mounted to the bottle cage mounts on your bike.
I got the 100cc pump because I’m not overly concerned about the insignificant more weight or the slightly longer size of the pump, and you get 30% more air in per pump. I definitely could tell how much difference the extra volume made when I had to use it to fix flat tires compared to other hand pumps that I’ve used. There wasn’t any lever that you have to flip to get the pump to lock on to the presta valve, just push it on and start pumping. I also like how you can carry your CO2 inside the end of the pump, where you can also fit the EDC tool.
I don’t have any really bad to say about the functions of the pump itself, most of my issues started happening when I put the tool inside the pump. One thing that I have very minor issues with is that to used the CO2 adaptor, you need to unscrew it from the head of the pump and then screw the CO2 on. It works fine, but can take some time. If you’re not racing, this wouldn’t really be an issue, but if you’re in a very long enduro stage and puncture a tire, every second counts and there are other adaptors out there that are much quicker to use. The pump only works on presta valves, and with pretty much all newer bikes, and all tubeless setups being presta, this hasn’t been an issue for me or anybody that I’ve come across who’s needed a pump. If you’re using tubes with schreader valves, this pump is unfortunately not for you.
After getting a new fork and not having the tap to put my EDC tool in the steertube, I put it in the pump for a while until I could borrow a tap. I wasn’t really that happy using the pump and the tool in this configuration though. To be able to get the tool out, I always had to take the pump out the holder due to the very tight seal that the oring on the tool had to keep it from popping out of the pump/steertube. To get it back in, I sometimes had use a lot of force to push the bottom of the tool against a hard object to get the tool to lock into the pump. I guess is a bit of a smaller problem if you don’t have to use the tool that often, but I think it’s worth mentioning since a big part of why I got the tool was easy and quick access. I also experienced the end of the pump extending and rattling against my frame when the extra weight of the tool pulled it out of the seal that kept the two moving parts together durning stowage. This only really happened on faster rough trails, but was pretty annoying, and enough for me to suggest people don’t carry their EDC tool in this configuration. Without the EDC tool in carried in the pump, this has yet to happen, even during racing.
The only structural issue I have with the pump isn’t even on the pump really. The elastic retaining strap that locks in the pump to the mount broke on me. surprisingly the pump hasn’t fallen out yet, so the mount itself has enough strength to hold the pump in place so far.
It seems like there are a lot more negative things than positive, but that’s not true when I’m talking about the pump itself. The pump itself has exceeded all other pumps I’ve used in performance and reliability so far. I have not attempted to seat a tubeless tire with it yet, but I wouldn’t be surprised if it worked without too much effort. I’m not a big fan of carrying the EDC tool inside the pump, mostly for accessibility of the tool. I know other people who carry the tools inside their pumps and don’t have issues with the end of the pump coming loose and rattling against the frame, so maybe I just got a loose seal or something. Overall, I would recommend the One Up EDC Pump to use as a hand pump to keep on your frame on in your bag, that can also carry a CO2 in the storage compartment for quicker repairs.
